In the production of timber boards roughly 50% of the log is used for this purpose and the other 50% is used for pulp. Bark, wood chip and sawdust are used in the biofuel industries and also used to provide heat for the mills themselves and specifically the kilns.
Timber is sorted into groups with similar appearance or structural properties in each group. Inevitably there is a small overlap of properties within a group.
Timber is specified by its grade and the implied properties and characteristics of each grade.
The sorting of visual products for their aesthetic purposes is quite different to the sorting of structural products for their strength characteristics.
The visual/aesthetic grading process for redwood takes into account many different parameters including; knots, fungus, twist, discolouration, crookedness, cracking, bark, top fracture, handling damage, dull edges, compression and size deviation. The timber is graded from I through to VI with I being the highest grade.
Strength grading assesses fewer parameters focussing mainly on, knots, twist, holes & fungus. Strength grades range from C14 – C35.
